Runtime Localization (multi-language) Not Working On Some Devices Ex. Oppo F9 And Huawei Y9

I implemented the following Localization logic in order to be able to change the language of my app dynamically from English to Arabic and vice-versa. It is working on all emulator

Solution 1:

I was able to solve this issue by generating a signed APK (as I usually did before signed bundles existed), then uploading it to google play.

Using the Generate signed bundle was causing this issue on some devices when they download the app from google play, while others had no problem so it was confusing.

My app size got somehow larger by an extra 3MB, but at least it is working properly on all devices right now when users download it from google play (Mine and on the devices of users that complained to have problems)
